GAGE-WHEEL FOR SCARIFYING DEVICES.

Specification of Letters Patent. Patented Aug; 23, 1921.

Application filed September 13, 1920. Serial No. 410,069.

To aZZ whom it may concern Be it known that I, HENRY D. JoNEs, a citizenof the United States, residing at Springfield, in the county of Clarkand State of Ohio,-have invented certain new and useful Improvements inGage-Wheels for Scarifying Devices, of which the following is aspecification.

This invention relates to improvements in scarifying devices of the kindwhich are attached to the rear end of road engines, it relating moreparticularly to a novel construction of gage wheel for use in connectionwith such devices.

One of the objects of my invention is to provide a gage wheel soconstructed and associated with the scarifying tools as to preventclogging of the road material, earth or trash between the wheel and theadjacent tool.

A further object of my invention is to provide a gage wheel sovconstructed as to obviate side strain upon the parts.

In the accompanying drawings Figure 1 is a rear view of so much of aroad engine and the scarifying devices as is necessary to illustrate theinvention, showing my improved gage wheel applied thereto.

Fig. 2 is a vertical section of one of the gage wheels.

The scarifying devices which I have shown are constructed substantiallylike the scarifier illustrated in my prior Patent No. 1,226,528 datedMay 15, 1917. The scarifier devices are attached to the rear end of thetank 1 of the engine by providing a frame consist ing of the uprightsupporting members 2 and 3 bolted or otherwise firmly secured to thetank. The lower end of this frame has bearings i in which is journaled adraft bar 5 to which are keyed a series of tool holders 6, to the rearfree end of which are clamped the ground breaking tools 7. Connectedwith each of the tool holders 6, at points adjacent the rear end thereofis a shaft 8 which projects laterally beyond the series of tools at eachside of the machine and has jourlnaled thereon gage wheels 9. A fluidpressure cylinder 10 has its upper end pivoted on a shaft 11 supportedby the upper end of the frame members 2 and 3 and the piston rod 12 ofthe piston of this cylinder is connected to a yoke-shaped member 13journaled on the shaft 8 so that the scarifying devices may be raisedand lowered and pressure applled thereto 1n the manner described 1n myprior patent referred to.

In the use of such devices, difficulty has been encountered with trash,such as the hard surface of roads, lumpy earth, or other substancesencountered, accumulating between the gage wheel and the adjacent toolwhen the gage wheel is constructed in the usual and ordinary manner suchas shown in my prior patent referred to. Further, these gage wheels asheretofore constructed are the cause of considerable side strain uponthe parts, particularly when the machine is making turns or being moveddiagonally across the road, which has resulted in straining the tank tosuch an extent as to cause it to leak as well as bringing undesirablestrain upon the operating parts. To obviate these difliculties I havec011- structed each of the gage wheels as follows The hub 14; of thewheel is connected to the inside edge of the tread 15 thereof by a webportion 16. This web portion 16 con nccts with the hub at a pointadjacent its inner end and projects inwardly toward the center of thewheel so that the outer portion thereof will connect with the tread 15at a point which will be substantially on a line with. the center of thehub so that the web projects at an angle outwardly away from theadjacent scarifying tool so as to form in effect with the tool anoutwardlv flaring throat. As a result of this construction the trashwhich is encountered between either one of the gage wheels and itsadjacent tool will he allowed to escape freely from be tween the same,being assisted in this 1: .spect by the rotation of the gage wheel.

The respective edges of the tread portion 15 of each gage wheel areformed on the arc of a circle or rounded, as indicated at 15 and 15, asa result of which the wheels are permitted to more readily ride out ofruts and depressions encountered and thus obviateto a large extent sidestrain upon the parts.

The hub, tread, and web are all preferably formed integrally and aseries of webs 17 are preferably provided for strengthening purposes.

Having thus described my invention, I claim 1. In a scarifyingapparatus, a series of scarifying tools, gage wheels associatedtherewith, theside of each wheel being inclined outwardly away from its.adjacent tool, for the purpose specified.

2. In ascarifying apparatus, a series of pivotallysupported tools, gagewheels connected with said tools, one at each end of the series thereof,each gage wheel being provided with a web portion which is inclinedoutwardly away from its adjacent tool, for the purpose specified.

3. In a scarifying apparatus, a scarifying tool, a gage'wheel adjacentthereto, said gage wheel having a hub and a tread portion, a webconnecting the same, said web being connected with said hub at a pointadjacent its inner end and extended out- HENRY D. JONES.
